Four women were arrested during a prostitution sting Tuesday along East Michigan Avenue in Ypsilanti and Ypsilanti Township, police said.

It marks the fourth prostitution bust in the area in eight weeks.

Ypsilanti police officers and Washtenaw County sheriff's deputies teamed up for the operation that ran from 3 p.m. to 11 p.m., an Ypsilanti police news release said.

The women were arrested for solicitation for prostitution and taken to the Washtenaw County Jail. Charges are pending.

The sting was part of a program called Enforcement Against Street Walking in Ypsilanti (E.A.S.Y.).

The effort brings law enforcement, human services, the judicial system and elected officials together to address the root causes of prostitution and keep people off the streets. So far, the program has worked with 12 women, the release said.

Other prostitution busts in the area occurred June 22, June 9 and May 4, resulting in the arrests of 15 men for solicitation of prostitution and 6 women for solicitation for prostitution.
